The aim of organizational effectiveness research is to increase human performance effectiveness in an organization and to improve teamwork and job satisfaction, by developing diagnostic instruments to identify problem areas, intervening with organizational development techniques to correct the problems, and finally evaluating the intervention results in terms of productivity and job satisfaction. A diagnostic Work Environment Questionnaire (WEQ) was developed and validated over a 3-year period at an Army field installation. It elicited from both supervisors and subordinates their attitudes and perceptions on their job duties, training, performance standards and consequences, and on their organizational supervision, work group, job importance, and feedback. Some findings are discussed.
